WATER-CALMING DEVICE.

Specification of Letters Patent.

Patented May 11, 1915.

Application filed October 27, 1914. Serial No. 868,880.

To all uhom it may concern:

Be it known that I, Jnssn F. WHITE, a

citizen of the United States, residing at Titusville, in the county of Brevard and State of Florida, have invented new and useful Improvements in Water-Calming Devices, of which the following is a specification.

This invention relates to water calming devices, the object in view being to provide simple means adapted to be placed at the most efficient ooint and to be operated for the purpose 0 calming the water in the immediate vicinity of the position of the device.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated and claimed.

In the accompanying drawings :-Figure 1 is a front elevation of a boat showing the calming device of this invention in its applied relation thereto. Fig. 2 is an enlarged view of the device, partly in elevation and partly in section. Fig. 3 is a fragmentary horizontal section taken just above the propeller.

The device contemplated in this invention comprises essentially a screw propeller 1 which preferably has a very light pitch and which is turned in a direction which will cause it to have a lifting effect on the water in which it is submerged while in action.

The propeller 1 which is of the screw type is fast on the lower extremity of a substantially vertical propeller shaft 2 which extends upwardly through a tubular housing 3 secured to a supporting base 4: at its lower end, said base I being just above the propeller 1 so as to prevent the propeller from coming in contact with the side of a vessel or any other object in proximity to which the device is used.

In the preferred embodiment of this invention and for the sake of convenience, a motor 5 such as an electric motor is mounted upon and supported by the housing 3 and serves to actuate the propeller shaft 2, the current wires being led to and from the motor 5 so that the device as a whole may be lowered into the water from the deck of a vessel, for example, until the propeller 1 is submerged to the required depth.

A suspending eye 6 is arranged at the upper extremity of the device as shown so as to enable block and tackle mechanism or other raising and lowering mechanism to be attached to the device to enable the same to be properly handled.

\Vhen the device is lowered into the water and the propeller l operated, it acts with a lifting effect on the water and thus breaks up the continuity of the waves, producing a counter-turbulence which results in producing a comparative calm in the water in the vicinity of the device. Any number of such devices may be used in connection with a single vessel and by equipping each with an independent motor, the devices may be shifted from place to place without disarranging the motive power.

7 designates a rudder against which the current acts for the purpose of maintaining the entire device in proper relation to the vessel from which it is lowered into the water.

8 designates a shield designed to protect the motor 5 from becoming saturated with water in a heavy sea.

What I claim is 1. Means for calming turbulent water, embodying a submerged water lifting screw propeller revoluble on a substantially vertical axis, and driving mechanism for said propeller.

2. Means for calming turbulent water, embodying a submerged water lifting screw propeller revoluble on a substantially vertical axis, a substantially vertical shaft for driving said propeller, a housing for said shaft, a supporting base to which said housing is attached, and a suspension eye at the upper extremity of said housing.

3. Means for calming turbulent water, embodying a submerged water lifting screw propeller revoluble on a substantially vertical axis, a substantially vertical shaft for driving said propeller, a housing for said shaft, a supporting base to which said housing is attached, and a motor supported by said housing for driving said shaft.

In testimony whereof I affix my signature in presence of two witnesses.

JESSE F. WHITE.
